Novel broad band excitation of Er/sup 3+/ luminescence in chalcogenide glasses

Chalcogenide glass is an attractive material for Er/sup 3+/-doped planar waveguide devices operating in the 1550 nm range because of the ability to pattern waveguides by photodarkening, infrared transparency and high refractive index, and ease of thin film deposition. In this paper, we present an in...

Zusammenfassung:Chalcogenide glass is an attractive material for Er/sup 3+/-doped planar waveguide devices operating in the 1550 nm range because of the ability to pattern waveguides by photodarkening, infrared transparency and high refractive index, and ease of thin film deposition. In this paper, we present an investigation of optical properties of Er/sup 3+/ doped Ge/sub 33/As/sub 12/Se/sub 55/ glasses. The samples were investigated by photoluminescence (PL) and PL excitation spectroscopies.
